Releasing Gemma 4 Under Apache 2.0 Is A Big Deal

Google has released its Gemma 4 model under an Apache 2.0 license, and that's quite a big deal. The Apache License 2.0 is a permissive, business-friendly open-source software license developed by the Apache Software Foundation. It allows users to freely use, modify, distribute, and sublicense software, including for commercial purposes. For enterprises, that's important because it allows you to take open-source code and make it proprietary, meaning you do not have to share your modifications.
